Slaves is the term given to systems which you have gained access to, and extends to cover players and NPCs while ingame, despite the two being considered separate elsewhere.
Slaves are the primary way to earn money in SlaveHack. Varying types of Virus's are uploaded to Slave in order to earn money. Non-NPC slaves are capable of fighting back against your intrusions of their system, deleting your files and possibly intruding into your own system.
NPC Slaves Edit
NPC Slaves are the key to becoming a better hacker, as they contain stronger and better pieces of Software and Virus's. Throughout the game there is a Riddle Trail which will lead you from one system to another in order to get better grade Software and Virus's.
